Scent detection dogs detect a species of hard tick, Dermacentor albipictus, with comparable accuracy and efficiency to traditional tick drag surveys Scent detection dogs detect a species of hard tick, Dermacentor albipictus, with comparable accuracy and efficiency to traditional tick drag surveys

Background Accurate surveillance data are critical for addressing tick and tick-borne pathogen risk to human and animal health. Current surveillance methods for detecting invading or expanding tick species are limited in their ability to scale efficiently to state or national levels. In this study we explored the potential use of scent detection dogs to assist field surveys for a hard...

High-precision U-Pb data and reference age for Emerald Lake apatite High-precision U-Pb data and reference age for Emerald Lake apatite

New isotope dilution thermal ionization mass spectrometry U-Pb data for Emerald Lake apatite demonstrate its potential as a reference material for geochronology. A three-dimensional 238U/206Pb-207Pb/206Pb-204Pb/206Pb isochron produces a 95.2 ± 1.1 Ma date with an initial Pb isotopic composition of 206Pb/204Pb = 18.85 ± 0.19 and 207Pb/204Pb = 15.68 ± 0.10 (n = 5, MSWD = 9.5). These data...

Simulating demography, monitoring, and management decisions to evaluate adaptive management strategies for endangered species Simulating demography, monitoring, and management decisions to evaluate adaptive management strategies for endangered species

Adaptive management (AM) remains underused in conservation, partly because optimization-based approaches require real-world problems to be substantially simplified. We present an approach to AM based in management strategy evaluation, a method used largely in fisheries. Managers define objectives and nominate alternative adaptive strategies, whose future performance is simulated by...

Low genetic differentiation across restored and natural populations shortly after a large-scale, post-fire seeding in the Great Basin Low genetic differentiation across restored and natural populations shortly after a large-scale, post-fire seeding in the Great Basin

Genetic diversity is essential for species to adapt to environmental changes. In restoration efforts, such as those after large wildfires in the sagebrush steppe of the Great Basin, commercially produced native seeds are used to revegetate the burned areas. While native seed certification and procurement protocols assure that genetically appropriate seeds are used for restoration, how...

U.S. Geological Survey global seabed mineral resources U.S. Geological Survey global seabed mineral resources

The U.S. Geological Survey (USGS) provides science and data on seabed mineral resources and ecosystems, as well as on the potential hazards associated with extraction. The Nation relies on minerals for infrastructure, technology, manufacturing, and energy production. Critical minerals are essential to the economic and national security of the United States and have a supply chain...

Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Version 4 product user guide Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Version 4 product user guide

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is a multispectral imager that was launched on board the National Aeronautics and Space Administration (NASA) Earth Observing System (EOS) Terra Platform on December 18, 1999, and has been observing and collecting Earth observations for over 25 years. ASTER covers a wide spectral region from visible to thermal...
